Purpose/Significance Starting from the early features of emerging research topics and the characteristics of weak signals, this study aims to achieve early identification of emerging research topics through weak signal analysis based on multi-source data.
Method/Process First, four types of data sources—patents, clinical, news articles, and academic papers—were utilized to extract topics using the BERTopic model and to construct a composite indicator of “emergence” for identifying emerging research topics. Next, based on topic visibility and topic diffusion, topic emergence maps and topic allocation maps were constructed to identify emerging research topics characterized by weak signals. Under the framework of multi-source data cross-validation, the potential influence of these topics was assessed. Finally, an empirical analysis is conducted in the field of stem cells.
Result/Conclusion The empirical findings indicate that the weak signal-based emerging research topics identified in this study align more closely with the technological directions outlined in authoritative reports, high-impact journal publications, and specialized academic guidelines compared to other types of topics, and they exhibit strong cross-domain influence. The proposed early identification method for emerging research topics, based on weak signal analysis of multi-source data, not only enables early detection but also enhances the accuracy and coverage of topic identification through integrated multi-source data.

目的/意义 从新兴研究主题早期特征和弱信号的特性出发,通过多源数据的弱信号分析方法实现新兴研究主题的早期识别。
方法/过程 首先,采用专利、临床、新闻和论文四类数据,利用BERTopic模型获取主题,构建新兴度综合指标识别新兴研究主题;其次,基于主题可见度和主题扩散度,构建主题涌现图、主题分配图,识别弱信号新兴研究主题,并在多源数据交叉验证下,测度其潜在影响力;最后,使用干细胞领域开展实证分析。
结果/结论 实证发现,本文识别的弱信号新兴研究主题较其他类型主题更符合权威报告、权威期刊论文、专业学术指南的技术方向,具有较强的跨领域影响力。本文构建的基于多源数据弱信号分析的早期新兴研究主题识别方法,可以实现新兴研究主题的早期识别,且通过多源数据整合提升了识别的准确性与覆盖度。
